Borophagus is an extinct genus of the subfamily Borophaginae, a group of canids endemic to North America from the Middle Miocene epoch through the Late Pliocene epoch 12—2 Mya.
Aelurodon is an extinct canine genus of the subfamily Borophaginae which lived from the Barstovian land mammal age of the middle Miocene to the late Miocene epoch. Aelurodon existed for approximately 10.7 million years .
The extinct Borophaginae form one of three subfamilies found within the canid family. The other two canid subfamilies are the extinct Hesperocyoninae and extant Caninae. Borophaginae, called "bone-crushing dogs", were endemic to North America during the Oligocene to Pliocene and lived roughly 36—2.5 million years ago, existing for about 33.5 million years .
Epicyon is a large, extinct, canid genus of the subfamily Borophaginae, native to North America. Epicyon existed for about 15 million years from the Hemingfordian age of the Early Miocene to the Hemphillian of the Late Miocene.
Hesperocyon is an extinct genus of canids that was endemic to North America, ranging from southern Canada to Colorado. It appeared during the Uintan age–Bridgerian age (NALMA) of the Mid-Eocene 42.5 mya—31.0 Ma. (AEO). Hesperocyon existed for approximately 11.5 million years .
Cynodesmus is an extinct genus of omnivorous canine which inhabited North America during the Oligocene living from 33.3—-26.3 Ma and existed for approximately 7 million years .
The Caninae, known as canines, are one of three subfamilies found within the canid family. The other two canid subfamilies are the extinct Borophaginae and Hesperocyoninae. The Caninae includes all living canids and their most recent fossil relatives. Their fossils were first found in North America and dated to the Oligocene era, then spreading to Asia at the end of the Miocene era, some 7 million to 8 million years ago.
Tomarctus is a canid genus of the extinct subfamily Borophaginae which inhabited most of North America during the late Early Miocene to the Early Barstovian age of the Middle Miocene. Tomarctus existed for approximately 6.83 million years .
Cynarctus is an extinct genus of the Borophaginae subfamily of canids native to North America. It lived during the Middle to Late Miocene 16.0—10.3 mya, existing for approximately 5.7 million years . Fossils have been uncovered in California, Maryland, western Nebraska, and Texas. It was likely an omnivore, and lacked the bone-cracking adaptations found in some later borophagines.
Borophagini is a clade or tribe of the subfamily Borophaginae. This is an extinct group of terrestrial canids that were endemic and widespread throughout North America and Central America which lived during the Geringian stage of the Oligocene epoch to the Zanclean age of the Early Pliocene living 30.8—3.6 Mya existing approximately 27.2 million years .
Borophagina is a subtribe of the Borophaginae, a group of extinct canids. They inhabited much of North America from the Early Miocene to the Zanclean stage of the Pliocene, 20.6—3.6 Mya, and existed for approximately 17 million years .
Canis edwardii, also known as Edward's wolf, is an extinct species of wolf in the genus Canis which was endemic to most of North America from the Late Blancan stage of the Pliocene epoch through to the Irvingtonian stage of the Pleistocene epoch, living 2.3 million years ago (Mya)—300,000 years ago, existing for about 2 million years .
Borophagus parvus is an extinct species of the genus Borophagus, of the subfamily Borophaginae, a group of canids (bear-dog) endemic to North America from the late Hemphillian of the Miocene epoch through the Pliocene epoch 10.3—4.9 Ma, existing for approximately 5.4 million years .
Borophagus dudleyi is an extinct species of the genus Borophagus of the subfamily Borophaginae, a group of canids endemic to North America from the late Hemphillian of the Miocene epoch through the Pliocene epoch. Borophagus dudleyi existed for approximately 5.4 million years .
Borophagus hilli is an extinct species of the genus Borophagus of the subfamily Borophaginae, a group of canids endemic to North America from the Late Miocene until the Pliocene.
Borophagus diversidens is an extinct species of the genus Borophagus of the subfamily Borophaginae, a group of canids endemic to North America from the late Miocene epoch through the Pliocene epoch 4.9—1.8 Ma.
Borophagus orc is an extinct species of the genus Borophagus of the subfamily Borophaginae, a group of canids endemic to North America from the 10.3 Mya to 4.9 Mya. Borophagus orc existed for approximately 5.4 million years .
Borophagus pugnator is an extinct species of the genus Borophagus of the subfamily Borophaginae, a group of canids endemic to North America from the early Miocene epoch through the late Miocene epoch 23.3—5.3 Ma. Borophagus pugnator existed for approximately 18 million years .
Borophagus secundus is an extinct species of the genus Borophagus of the subfamily Borophaginae, a group of canids endemic to North America from the Early Miocene epoch through the Late Miocene epoch. Borophagus secundus existed for approximately 17.7 million years .
